Has anyone bought the Ray Prouty book from helo books? On the site it says its a reprint of articles in rotor and wing. If it is a reprint of all three books its cheap at $60, at Barnes and noble, though they dont have any copies, their price is $200 per book, leaving me confused.
Could anyone who has purchased please let me know if it is a reprint of the volumes, or a reprint of the articles from rotor and wing.
Thanx again
